Keep line breaks when POSTing data with PHP curl

PHP
1

Hello!

I am currently trying to POST data from one server to another, but the information must be transferred in the same way that is was created (Formatting is very important).

I am sending this message:

begin-transmission
uib3qu9bvu3b8v48v8b408v
uo45bv4b5bh09n568vb904nv
ui45b89u4bt48v08942v0842nv
uiv84b8409vn849v8i4
uv84n0b49bn8409
vb3wur5vbwvb308vbq0v
end-transmission
Code 
$domain = "google.com";
$pkey = 'begin-transmission
uib3qu9bvu3b8v48v8b408v
uo45bv4b5bh09n568vb904nv
ui45b89u4bt48v08942v0842nv
uiv84b8409vn849v8i4
uv84n0b49bn8409
vb3wur5vbwvb308vbq0v
end-transmission';

$url1 = 'cp3.php';  //This is the URL I am using to check how the message is sent

$data = array(
    'domain_name'  => $domain,
    'key'  => $pkey
);

foreach ($data as $key => $value) {
    $fields_string .= $key . '=' . $value . '&';
}

rtrim($fields_string, '&');


$curl = curl_init();
curl_setopt ($curl, CURLOPT_URL, $url1);
curl_setopt ($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($curl, CURLOPT_POSTFIELDS, $fields_string);

$resp = curl_exec($curl);
curl_close($curl);

I kept getting invalid response error, so I changed the result URL to view what was being sent. This is what is being sent:

begin-transmissionuib3qu9bvu3b8v48v8b408vuo45bv4b5bh09n568vb904nvui45b89u4bt48v08942v0842nvuiv84b8409vn849v8i4uv84n0b49bn8409vb3wur5vbwvb308vbq0vend-transmission

Goal: To get the message transfered to the other server without loosing any line breaks so this other server can process it.

Note: I do not have access to this other server, and do not know how it processes the message. I am willing to do a bunch of trial-and-error tests though if there are multiple ways this could be done.

Thanks in advance for your help!

Well for starters, you havent told cURL you want to POST.

curl_setopt($curl, CURLOPT_POST, 1);

3

But it is still posting the data even without it being stated. I had that line in there before, but removing it or adding it does not make a difference (Since POST is set by default, and CURLOPT_POSTFIELDS sets the mode to POST).

4

You sure about that?

5

Added.

The line breaks are still not there though.

6

Can you please explain what server you want to reach and why he is expecting line breaks? As line breaks are not clearly specified as a character it is nearly impossible to define a standard interface which relies on line breaks. line breaks can be \n or even \r\n. How should the server know what is the correct one?

I guess you are completely on a wrong way so please give us more information about what you are trying to do.

7

also… how are you viewing what was being sent? The browser wont render line breaks in the HTML by default…

Hello again

I did a bit more experimenting, and found that if I send that data manually it works fine. But the PHP curl code still does not work right.

Could you figure out if I messed something up somewhere, because I honestly am totally confused.

Manual code (Works):


<form action="https://remoteserver.com" method="post" target="_blank">
    <input type="text" name="domain_name" value="domain.org">
    <textarea rows="40" cols="64" name="key">-----BEGIN MESSAGE-----
hfjehfienjfneif
Dndjfneknfkr
Fneifb4jrjfj3nfj
Rnfirndo393n
Nckenfo394nfje
Nfneo38
-----END MESSAGE-----</textarea>
    <input type="submit" value="Upload Message">

</form>

Automatic Code (What I want to work):

$domain = 'domain.org';
$pkey = "-----BEGIN MESSAGE-----
hfjehfienjfneif
Dndjfneknfkr
Fneifb4jrjfj3nfj
Rnfirndo393n
Nckenfo394nfje
Nfneo38
-----END MESSAGE-----";
$url1 = 'https://remoteserver.com/';

$data = array(
    'domain_name'  => $domain,
    'key'  => $pkey
);


$fields_string = 'domain_name='.$domain.'&key='.$pkey;


$headers = array(
   "Cookie: PHPSESSID=q1dsvk2eup504vlvifc1upviu2",
);

$curl = curl_init();
curl_setopt ($curl, CURLOPT_URL, $url1);
curl_setopt ($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt ($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($curl, CURLOPT_TIMEOUT, 60);
curl_setopt ($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($curl, CURLOPT_POSTFIELDS, $fields_string);
curl_setopt ($curl, CURLOPT_POST, 1);
curl_setopt ($curl, CURLOPT_COOKIESESSION, true);
curl_setopt ($curl, CURLOPT_FORBID_REUSE, true);
curl_setopt ($curl, CURLOPT_HEADER, 1);
curl_setopt ($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt ($curl, CURLOPT_MAXREDIRS, 10);
curl_setopt ($curl, CURLOPT_REFERER, 'https://Google.com');

$resp = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);


echo $status;
echo '<br>';
var_dump(htmlentities($resp));
?>

Its probably just a little mistake that I somehow missed.

Thanks in advance!

I seem to have passed the limit for editing the previous post, but I would also like to add that including \n at the end of each line in the second method (The one that does not work right now), still does not make a difference. Nether does using \r\n.

To anyone following, I finally got what the OP is attempting. He is trying to automate SSL Installs with cPanel. OP is an XY Problem.

To start, I found that when I explain the entire thing, I get a lot less helpful responces than when I post a little snippet. And those that do respond are not normally helpful. I also tend to get comments like “Why did you post all that irrelevant data”.

And if I post a smaller thing (Like my first post), I generally get better responces. And even if I was not exact on what the problem was, the reponces generally lead me in the correct way.

At first, I thought the issue was the spaces. I didn’t know how to add them, and my tests were coming back incorrect.
Now, I don’t know what the heck the issue is, so I posted this responce.

I feel that the more I add to the ‘story’, the less likely people are to respond with something that is actually helpful. And its not just a feeling, its happened before (Maybe the issue is that I am not very good at explaining).

So I generally do less explaining and let the code talk for itself. And in the past, that approach has worked a lot better than explaining the full and actual issue.
